The RIO Grand is a full line size heavier than the industry standard, and features more weight distributed towards the front of the line to easily load faster action fly rods. The line has a short head that is easy to cast, and is built with "MaxCast" Technology, RIO's ultra-sophisticated line coating that actively repels water for higher floatation, longer casts and greater durability. The RIO Grand is the best choice of line for the modern, fast action fly rod.
